Begin by washing your ripe plums and mangoes under cool running water. Slice the plums into thin wedges and the mangoes into bite-sized cubes.

Rinse and chop your chosen lettuce and baby spinach. Place all the greens into a large mixing bowl.

Carefully add your prepared fruit to the greens in the bowl and gently fold them together.

In a separate small bowl, combine honey, Dijon mustard, and vinegar until well blended.

Drizzle your honey-dijon dressing over the salad mixture and toss gently to coat.

Plate your finished salad immediately for optimal freshness.
